all weak ; a median marginal pair, and a single lateral marginal macrochifita on 
each side on first segment, a lateral and a median marginal pair on second seg- 
ment, third segment with about ten marginal ones ; anal segment with some weak 
discal and marginal macrocluet®. Legs blackish, femora and tibise somewhat 
cinereous, bristly, the tibise more strongly so. Claws and pulvilli very long. 
Wings grayish hyaline, longer than abdomen, moderately wide, with only two 
slightly longer costal spines at termination of auxiliary vein, third vein not 
spilled at base, apical cell open, terminating but little before tip of wing, bend 
of fourth vein rounded, without stump or wrinkle, hind cross-vein sinuate, 
nearer to the bend of fourth vein, tegulte smoky white, halteres flavous. Length 
7.5 mm. ; of wing 6.5 mm. 
Described from one specimen received from Mr. Chas. Robertson, 
Carlinville, 111. This species I have located temporarily in Masicera, 
although it does not (piite agree with the characters of that genus. 
The ajiical cell is opened only a little before the wing’s tip, and the 
form is rather narrower than is usual in Masicera. It apparently 
approaches Telothyria v. d. Wulp, but differs from it by the promi- 
nent front, receding face and distinctly 2-jointed arista. Additional 
specimens will be needed to decide its location.

Belongs in the Tachinince s. str., in section with bare eyes and 
apical cell closed in the margin. Head, thorax and abdomen nearly 
same width. Eyes bare, extending a little more than two-thirds the 
distance to the oral margin. Front nearly one-half the width of 
head, face wider; frontal bristles descending in a single row close to 
facial ridges as far down as lower border of the eyes; the bristles at 
the vertical angles and next one on each side directed backw'ard, rest 
above antennfe directed inward, those below anten me directed down- 
ward ; three orbital bristles, and sometimes other smaller bristles 
intermixed. Front almost in a horizontal plane, strongly projected 
forward. Sides of face rather wide above, narrower below, bare 
except for the row of frontal bristles ; cheeks bare, wude, nearly one- 
half the eye-hight, with some bristles on lower border; face strongly 
oblique, receding, facial depression very long, narrow, facial ridges 
bare ; vibrissae inserted on oral margin, not very long, decussate. 
Antennae about as long as the face ; first joint erect, rather short ; 
second joint about same length ; third joint not much wddened, but 
considerably thickened, very long, fully ten times the length of the 
second, apex angular on front border, rounded behind ; arista dis- 
tinctly 3-jointed, microscopically pubescent, thickened its whole
